8.1. Inspecting the Fiber Holding Blocks
The Fiber Holding Blocks (FHB’s) should be inspected daily for debris and/or damage that may prevent the lids
from closing properly and the fiber from being fully clamped. It is particularly important to make sure that the bottom
insert V-groove surfaces and the top insert clamping surfaces are free of debris and oils. This will help to ensure
that the fiber will not break or slip during tensioning. Remove debris using a nylon brush as shown below. Brush
from the inside to the outside of the unit as shown (away from the Cleave Blade) so as to avoid getting debris inside
the cleave assembly.
To remove oils from the inserts, use a cotton-tipped swab wetted with acetone or alcohol. Never do this while the
vacuum is turned on as the solvent will be sucked into the unit!
